onClick event in navigation drawer

Solution 1:

You need to add implements NavigationView.OnNavigationItemSelectedListener

public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener

and add method

@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
    // Handle navigation view item clicks here.
    switch (item.getItemId()) {

       case R.id.nav_maths: {
      //do somthing
            break;
        }  
    }
    //close navigation drawer
    mDrawerLayout.closeDrawer(GravityCompat.START);
    return true;
}

method to set Listener

private void setNavigationViewListener() {
    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);
}

call method in onCreate()

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setNavigationViewListener()
}

Solution 2:

Add NavigationItemSelectedListener event to nav_view

NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);

Implement your Activity with NavigationView.OnNavigationItemSelectedListener

and add this code for click item

@SuppressWarnings("StatementWithEmptyBody")
@Override
public boolean onNavigationItemSelected(MenuItem item) {
    // Handle navigation view item clicks here.
    int id = item.getItemId();

    if (id == R.id.nav_camera) {
        // Handle the camera action
    } else if (id == R.id.nav_gallery) {

    } else if (id == R.id.nav_slideshow) {

    } else if (id == R.id.nav_manage) {

    } else if (id == R.id.nav_share) {

    } else if (id == R.id.nav_send) {

    }

    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    drawer.closeDrawer(GravityCompat.START);
    return true;
}

Solution 3:

in your

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    if (aToggle.onOptionsItemSelected(item)) {
        return true;
    }
    return super.onOptionsItemSelected(item);

}}

add these lines:

switch (item.getItemId()) {
    case R.id.nav_maths:
        // your logic here.
        return true;
    case R.id.nav_physics:
        //your logic here
        return true;
    default:
        return super.onOptionsItemSelected(item);
    }

Solution 4:

Below code is for adding toggle to DrawerLayout

 DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
 ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
        this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
 drawer.setDrawerListener(toggle);

And to add listener to Navigation menu items

implements NavigationView.OnNavigationItemSelectedListener

and override below method

@Override
  public boolean onNavigationItemSelected(MenuItem item) {
    // Handle navigation view item clicks here.
    int id = item.getItemId();
    if(id == R.id. nav_maths){
      //Handle your stuff here
    } 
}

Add below code to onCreate method

NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);

Solution 5:

  @Override
    public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
        return false;
    }

get the Id with menuItem.getId() .And Perform Your Action as per your need.

final Step: Add This line in onCreate navigationView.setNavigationItemSelectedListener(this);

That's it.
